DEVICE FOR APPLYING GLAZING COMPOUNDS AND THE LIKE.

Application filed .Tune 13, 1919.

To all 'whom t may concern.'

Be it known that we, HERBERT B. SABIN and ORRIN C. SABIN, citizens of the United States, and residents of Cleveland Heights village, county of Cuyahoga, State of Ohio, have jointly invented a new and useful Improvement in Devices for Applying Glazing Compounds and the like, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention relates to devices for applying glazing putty or like compounds and it relates more particularly to a gun which may be operated by one hand, the operating mechanism being arranged so that the glazier can expel the entire charge from the gun without using both hands. It is particularly intended for use with the putty or compound used for filling the edges along panes of glass, such as is commonly used in green house construction, and 1s so arranged as to be suspended from the one arm ofthe operator, the mechanism for expelling the grease being operated by the hand, thus leaving the other hand and arm entirely free. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Figure l is a side elevation of our improved device; Fig. 2 is a longitudinal section through the same; Fig. 3 is a view of the pawl in its latch-releasing position; Fig 4 is a bottom plan view -of the nozzle; and Fig. 5 is a section on the line 5 5, Fig. 4.

In general construction, the gun ,consists of the usual barrel or cylinder 1 having threaded ends 2. On the forward end a cap 8 is threaded, which cap is provided with a discharge nozzle 4 to be described in detail hereinafter. A rear cap 5 is threaded on the other end of the barrel, this cap having an aperture through which extends the usual plungeror piston rod 6. Within thebarrel or cylinder is mounted a suitable piston 7 which in the form shown consists, of two Speccation of Letters Patent.

plates 8 with a cork disk 9 between the same, the piston rod 6 extending through alined apertures in the disk and plates. The rod is threaded at its forward end Aand a nut 10 is mounted thereon to clamp the plates tightly upon the disk and to hold the rod securely to the piston. This particular structure is not important and any other suitable piston may, of course, be used. t

At the forward end of the barrel a handle 14 is mounted, the handle being U-shaped in section and having a rearwardly extending upper end or projection 15 adapted to,

rest upon the hand of the operator to carry the weight. This handle is provided near the 'cylinder with an aperture 16 through which is movably mounted a rod 17. This rod extends in front of the handle and is provided with an upturned end 18 lying approximately parallel to the handle. Encircling the rodbetween the upturned end and the interior of the handle is a coiled spring 19 secured in position by a pin 20, the spring being adapted to maintain the rod in its forward position.

The rod 17 extends rearwardly along the cylinder, being bent to conform to the shape of the same and having a drop portion 21 so as to bring the rod to the rear at a point out of line with the forward portion of the rod. At its rear end, the rod extends outwardly from the barrel and is pivotally connected to an arm 22 which is in turn pivotally mounted on a lug 23 carried by the rear cap. This arm is formed of two plates so spaced as to receive the rod'therebetween, as well as the plunger or piston rod. In the other end of the arm, a movable pawl 24 is mounted, the pawl being normally in engagement with the series of teeth 25 formed on the plunger or piston rod. A flat spring 26 is carried by the arm and normally holds the pawl in its operative position. .The spring as shown is `so positioned that it will also hold the pawl out of engagement in the position shown in Fig. 4, the inturned end of the spring limiting the upward position of the pawl.

Cn the rear face of theV cap, a latch 27 is attached by means of a screw 28 passing through an elongated aperture in the latch, thus allowing limited movement of the same. On a boss 29 on the cap, a flat spring 30 is mounted, the spring extending over the upper face 31 of the latch and tending to maintain it in its position engaging the teeth on Price.

the piston rod. lThe latch is provided y with a shoulder 46 which is adapted to be engaged by theY pawl in its upper position. Movement of the rod 17 will then force the latch upwardly out of engagemay be returned to its filling position. The nozzle cap will then be removed and the gun refilled.

A very convenient and easily operated ment with the teeth on the piston rod and--gun is thus obtained and one which the opthe plunger may then be withdrawn by means of the small hand 47.

At the rear end of the cylinder a strap 32 is provided, which will be riveted or otherwise securely fastened to the cylinder or cap. The upwardly extending loop of the strap is adapted to encircle the arm of the operator and the strapk may be adjusted to fit the arm snugly by means of the buckle 33.

In operating the gun, the user extends his arm through the strap and grasps the handle, the extending piece of the latter resting upon the hand and carrying the weight. By extending his fingers, the operator grasps the upturned end of the rod and by moving the rod toward the handle, operates the arm at the rear to force the piston forwardly along the barrel by means of the pawl and ratchet mechanism, At each successive movement of the rod, the pawl will engage with and force the plunger rod into the gun, the latch preventing return movement of the plunger during the return movement of the rod and pawl. At the forward end of the movable rod, just rearwardly ofVV the handle, are a series of apertures 40 through which a cotter pin 41 may be placed to limit the forward aperture and each movement of the rod forces the plunger into the barrel a distance equal to one of the teeth on the piston rod. By moving the pin to the rear apertures, the movement of the plunger may be increased, as will be readily understood.

The forward cap is provided with a nozzle 4 which has its tip cut away at an angle as at 42, the sides of the cut-away portion ,being faced olf to provide a tip having an angular bottom, the two sides 43 lying approximately 90O from each other. In use on green houses, the tip is moved along the junction of the stringer and the glass, which are at approximately 90o to each other, thus allowing the grease or putty, as it is called, to flow out along the joint in the correct position to form asatisfactory sealing strip of putty. The upper portion 44 overhangs the angular bottom and allows the putty to flow out in the correct formto ll the space between the glass and sash.

, Thegun is carried andoperated by one varm and the user can also drop the handle of the gun, allowing it to swing from the arm when it isnecessary for him to use both hands. When the gun is empty the spring holding the pawl. is released and the pawl turned upwardly. rIhe operator then grasps the handle and by moving the operating rod, forces the pawl intol engagement with the latch to release the piston rod so that it erator can use with one hand. The grease can be readily expelled, the adjustment of the rod helping to determine the speed of flow. When it is necessary, the operator may use both hands, allowing the gun to hang from the strap. As the grease may be expelled either intermittently or continuously as desired, al very satisfactory gun is secured. Infilling the gun, thenozzle being removed, the operator holds the gun upright bythe handle and it is then easily filled, as it is in the most convenient position for this operation.

Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the .means stated by any of the following claims or the equivalent of such stated means be employed.
